Running two SIMS at the same time

I had a contract with 3 and a French eSIM with Lyca and could use both SIMs at the same time.  So when I am abroad, I can use the French eSIM for data but also have the 3 SIM turned on for phone calls to my normal number.

I have just changed to ID Mobile and I can only seem to switch between the two, and can’t have both switched on at the same time. If I toggle one on, the other goes off. So when I’m in France and using the French SIM, I can’t receive phone calls. 

Does anyone know how to get over this?

TIA

Maria

Assuming your iD SIM is an eSIM, does your phone support dual-eSIM use, ​@MariaSnail? 

Some phones are dual-SIM, but only one physical SIM and one eSIM can be active simultaneously in dual-SIM mode. 

Aha. You’re right. I have an iPhone 12 and I’ve just looked it up. It will run a physical SIM and an eSIM at the same time but not two eSIMs. I’ll have to see if I can get one of the eSIMs replaced with a physical one. THANK YOU!

    So the French Lyca SIM was a eSIM. So was the 3 SIM a physical SIM?

    What type of SIM is the iD SIM now that your using with the French Lyca eSIM?

    What make and model phone are you using?

    Hey there ​@MariaSnail, thank you for reaching out.

     

    As asked by ​@andewhite and ​@MZone, what make and model phone are you using please/

     

    Also, which SIMs are physical, and which are eSIM?

     

    Thanks,

    Hi Tyler, I have an iPhone 12. My previous SIM was a physical one and the Lyca and ID Mobile and eSIM. As @andewhite indicated, iPhone 12s don’t support two eSIMs, which explains why it worked before and now it doesn’t.
